Monarch article factful

To the editor:

My special thanks to Roland Hallee for his explanation of the Monarch butterflies’ migration journey. At last, after a lifelong interest, I “get” how it takes four generations. The whole article (The Town Line on October 5, 2017) is fact-filled and very easy to read. I enjoy The Town Line as a subscriber and always find something of special interest. The butterfly article is especially special.
